I run Photoshop CS3, Flexi 8.1 and I do lots of vehicle wraps. What is the best way to blow up artowrk? I have used Photozoom Pro2 with fair results but really would love to know "everything" there is to know about phot resizing. Any suggestions?
There is only one thing you need to know about enlarging bit maps. When you enlarge a bit map, pixels which did not exist must be created. Information which did not previously exist must be conjured up out of whole cloth.
The only reasonable way to do this is to extrapolate the value of a new pixel from those existing pixels around it. If you're enlarging by a small factor then it's fairly simple. Doing a significant enlargement can leave vast tracts of pixels which must be created. Calculating the value of a single new pixel surrounding by original pixels is fairly simple. Calculating the values of a group of new pixels is not so simple.
There are many algorithms to do this, some are better than others. All of them, each and every one, function by merely taking a guess.
Those who think that doing a series of incremental enlargements is somehow a better solution than going for it in one step are ignoring the inarguable fact the doing it either way results in exactly the name number of interpolated pixels and, worse, exactly the same number of pixels interpolated from pixels that were themselves interpolated in a previous step. Computers, being the single minded things that they are, can only create one pixel at a time regardless of doing an enlargement in steps or all at once.
